Hi everybody,<br><br>As the Asterisk community is getting larger and larger, I was wondering that the features which are provided in Asterisk and are programmed by the open source community under GPL, or GUIs like FreePBX which also come loaded with wonderful features and uses same Asterisk, are they anywhere violating any patent laws? Most of the features work the same way as Nortel, Avaya and other PBX systems. Is there anyone who owns these features and will come one day to claim his royalties?
<br><br>When I deploy an asterisk soultion for a customer, is there any violation of any patent or copyright laws anywhere? Of if I use my own Asterisk server to provide services to some customers, am I violating any patent laws by not paying the royalties to some patent owners?
<br><br>I heard people saying that IVR technology is patented and google search for patents also say so. But we all are using IVR for ourselves and our customers without paying royalties to anyone. But when it comes to using g729, all of a sudden royalty issue comes in.
<br><br>So what is right to use and what is not?<br clear="all"><br>-- <br>Zeeshan A Zakaria
